New Miocene Icarops material (Microchiroptera: Mystacinidae) from Australia, with a revised diagnosis of the genus SUZANNE HAND, MICHAEL ARCHER & HENK GODTHELP HAND, S.l., ARCHER, M. & GODTHELP, H., 2001:12:20. New Miocene lcarops material (Microchiroptera: Mystacinidae) from Australia, with a revised diagnosis of the genus. Memoirs of the Association of Australasian Palaeontologists 25,139-146. ISSN 0810-8889 New fossil material referable to Icarops paradox Hand et al., 1998 is described from the early Miocene Judith's Horizontalis Site in the Riversleigh World Heritage Property of northwestern Queensland. Fused dentaries contain the partial lower dentition of I. paradox. The diagnosis of the genus Icarops is revised. The new material confirms the identity of Icarops species as mystacinids and enablesre-examination of interrelationships between extinct and extant members of this Gondwanan bat family. S.J: Hand, M.
